BILLET THERMOSTAT HOUSING
Its well worth the money, as it will last a lifetime and you wont ever replace it. Built really well. The stock pot metal one is bound to need replacing as it will eventually pit. Clay I have a suggestion, you should make a Billet Lower Elbow as well.

Better than original
It has only been installed a couple weeks, so time will tell for sure. Installed with Motorcraft t stat and gasket. No leaks so far. Seems much better than OE pot metal design.

High Quality
Purchased this high quality part after a recommendation from Stephen Cox on YouTube. Quality manufacturing it’s too pretty to put on my 7.3 power stroke diesel. Considering purchasing the lower curved piece next.

No More Leaks
Fought the stock leaking thermostat housing for years. I can not remember a time when I did not have anti-freeze crust all over the area. Bought this and used a good thermostat sealant around the edge and no more leaks. Nice part!!

Riffraff Diesel 7.3L Billet Thermostat Housing
Probably overkill , but I had to replace OEM that was pitted, corroded. A little price to pay for some Bling that only you will probably see. Thanks, Riffraff

7.3 Billet Thermostat Housing
Very nice product is always what to expect from Riff Raff Diesel.
Counter bored bolt provisions with stainless hardware make a nice addition to the billet housing which is a great improvement over the stock housing. Be sure to purchase the correct size Allen Hex for the bolts! -
